Seann William Scott was once asked what his mother thought about his appearance as Stifler in the American Pie films. "She's not the kind of lady you'd think would love them, but as she's gotten older, she has let her hair down a little and likes to party," he replied. "She'll be in the grocery store telling people, 'Hey, I'm Stifler's mom -- I'm the MILF.' I'm, like, 'Mom, you really shouldn't say that...'"
MILF, of course, is an acronym -- for "Mom I'd like to f---."
